Sneeiention feliciteren- 0f vLetters Peten# No 114,139.1,.doied .illes/.9, 1871-' To all Itollem it .may concern Be it known that I, PHILIPPE Koen, of

Mnnehesrer, England, here invented feertein new and .useful Improvements in lllleehlnery for 'ManufacturingUntapped `Nuts for Screw` Bolts, reference -heine: `had tov lthe eeoexnpelnyingdiewihg's, forming .n pent of this sneeitiea# tion. y t

The object lof lthis invention lis vto' make smooth and well-shaped Auntapped nults'imuch more expeditiously: than has hithertobeen eieeted,`end for .this purpose I employ Vinoproved duplex .mechanism lwith ,movements working horizontellathene vbeine .n double entier, .two .engelen-.edged ours, hwornnehes, and two,iiattenersmovingto and fro successively, and two sets of herninershnvine sonipound up-and-down and to-and-fro motions, actingon abar Iof heated metal moved forward on one edge, the whole of the movements being operated at the required ltimes by two sets of similar cams working two sets of levers and corresponding parts.

Figure lis a front elevation, and Fig. 2a plan of my improved machinery for making square untapped nuts. Fig. 3 is a transverse section of Fig. 1 on the line A B. Fig. 4 is a vertical section of part of one side of the machine. Fig. 5 is a transverse section of Fig. 2 on the line C D. Fig. 6 is a plan showing some of the working parts of one side of the machine. Fig. 7 is a plan, partly in section, of some of the working parts of both sides.

The two sides of the machine, with their pointsof resistance, their workin g parts, and modes of operation, are precisely similar, and, therefore, if, after a general description of some of the parts, one side is minutely explained, the whole of the machine will be clearly understood; and I may here remark that when the word nuts is used, I mean the untapped nuts referred to in the title.

On the cross-bars a of the main frame-work there are twopairs of bearings or pedestals b, carrying the pivots or shafts c of two cylinders d, to which are xed a number of cams, and to the pivots or shafts at one end are fixed toothed wheels e, of equal size, gearing into each other, and on one pivot or at the end of one shaft there is a driving-pulley, f. To the cross-bars a are fixed an upright frame,

y, andtwo tables Il, there beineeinen toe-eeh labile a block, e', having slots or .guidesin .whiehlareplnoed slides for working ,n nangn- .1er-.edged ehn, n ..pnneh, enel .e iinfttener and in 4the .hleekis there vare `slots .on anillos .in whieh the lower `ends Iofthe .traveliugpteinelo nire ihleeed," .the .upper .ends fitting .slots .or guides .in'thosmauname 'z fixed to thejrgppf thennfieht freine o; and tothe .midflleof the jtierelin'g tranne' is'. fixed the .donbleentterim there l,being to-andfro-horizontel motiongiyen 'to'the .traveling frame and cutter ,by theearns non .theeyllndens'd .In front .of ,the .upright freiner there .is .n holzlzoniel nesseee,o`,.he tween two xed cutters waffen .lendihg .the ,heated .her refrein lwhioh .thengitsaretohe made, .in lfront ,o f the cutter nqtlle end .of Qca-G11 side 'of the .passage A.neen the entier' heine ,nihde aten enele eonvergingnp-ward, es seen in g.`1,v ordownward for enabling thel cutter to aston ,the .metel .by degrees, .instead of at .one absolute Vthnist, endtheieen .bnn isnhshged forward on its edge lwithout any turning over from one side to the other.

In each block fi, directly opposite each cutting side of the cutter, there is a stationary pin, q, Figs. 5 and 7. Inthe middle of the angular-edged cup r, at the eudof the slide s, which is moved forward by the cam t and backward by a spring, and near the cup, the punch u is fixed to the slide o, which is moved forward by the cam w, and returned by the spring a on the table h. At each side of the upright frame there are two hammers, y a, having slots working on studs xed to the frame, each hammer being formed at its acta ing part of two sides ot'- a square or other suitable shape; and ina groove in the table h there is a slide, a', having at the front end a attener, b', and below the table a spring4 support, c', Figs. 5 and 6. When the machine is set to work, and the heated bar p pushed through the passage o, the cutter m, as it advances, cuts oi' a blank and pushes it against the stationary pin g, Figs. 5 and 7, and then the cup r is pushed forward by the cam t to chamfer the blank, which is held by the pin q, when the -action of the cam ceases, and the cup is pulled back by its spring. The hammer y is now moved forward by the cam f and levers g Vh', so that its and the four sides of the blank are squeezed and nished by the hammers,and the blank immediately punched by the punch u, the hammer y'having an upward movement by the action of the cam k 4and lever l', and the hammer z having a forward movement by the side action of the` cam m on the toothed wheel e, and a downward movement by the action of the projection n on the rocking-shaft o', having at the back a lever, p, acted upon by the front surface of the cam m on the toothed wheel e, the return movements of the hammers being effected by the springs qw". The cams now cease their action on the two hammers, and the spring q pulls back the hammer y, and the hammer z descends, by the action of the cam t and lever u' to place the nut on the spring-support c', in front of the flattener b', which now comesforward, by the action of the cam t', slide w, and lever to flatten and finish the top and bottom of the nut; and when the hammer z is returned by the spring r1, the hammer y, in its next forward movement, forces back the spring-support c to allow the nut to fall by its own gravity to anyy required place or receptacle. As before stated,

both sides of the machine are alike, the movements of one side being followed by those of the other side, for when on one sidevtheinut is,

flattened, the traveling frame 1Q, ,with its double cutter m, is immediately acted-upon by the cam n on its opposite' sid e,;and theoperationsm before described take place on both-sides suc- E.

cessively, the cutter at each to-and-fro stroke forming straight and even edges as it leaves the blank 5 and as the heated bar of metal has only to be pushed onward Without turning, and the movements follow each other with great rapidity, an immense number of nuts are manufactured in a short time,

1. The pair of fixed cutters and the doubleacting cutter, combined and operating together in such a manner that without turning the heated iron bar the blanks are cut ol` f with all their square edges on one side.

2. In a machine for making untapped nuts,

the duplex fixed and movable cutters, constructed and arranged as herein described, in combination with the fixed pin and movable cup, and all arranged to. operate successively in the formation of the nuts, substantially as set forth.

. 3. In a machine for making untapped nuts, y

the duplex fixed and movable cutters and the fixed pin and movable cup, in combination with the aforesaid two hammers, and all arranged to operate successively in the formation of the nuts, substantially as set forth.

4. In a machine for manufacturing untapped nuts, the .duplex and double-acting mechanism consisting of the aforesaid'x'ed and moving cutters, the fixed pins, and movable cups, and the peculiarly-operating hammers, in combination with the cam-springs and other devicesherein described, or their equivalents, for impar-ting the required motion to the moving parts of the mechanism, substantially as herein. set forth.
